0Windshield wipers off
IIntermittent wiping
IINormal wiper speed
IIIFast wiper speedIntermittent wiping
Intermittent wiping interval is dependent
on wetness of windshield.
Turn the combination switch to
positionI.
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.
!Do not operate the windshield wipers
when the windshield is dry. Dust that
accumulates on a windshield might
scratch the glass and/or damage the
wiper blades when wiping occurs on a
dry windshield. If it is necessary to op-
erate the windshield wipers in dry
weather conditions, always operate the
windshield wipers with windshield
washer fluid (
page 55).
!Do not leave windshield wipers in
intermittent setting when the vehicle is
taken to an automatic car wash or
during windshield cleaning. Windshield
wipers will operate in the presence of
water sprayed on the windshield, and
windshield wipers may be damaged as
a result.!If you have set intermittent wiping, dirt
on the surface of the rain sensor or op-
tical effects may cause the windshield
wipers to wipe in an undesired fashion.
This could then damage the windshield
wiper blades or scratch the windows.
You should therefore switch off the
windshield wipers when weather condi-
tions are dry.
iIntermittent wiping is interrupted when
the vehicle is at a standstill and a door
is opened. This protects persons get-
ting into or out of the vehicle from be-
ing sprayed.
Intermittent wiping will be continued
when
all doors are closed
and
the gear selector lever is in position
D or R
or
the wiper setting is changed using
the combination switch.
55 Getting started
Driving

Press the combination switch briefly in
direction of arrow1 to the resistance
point.

Wiping with windshield washer fluid
Press the combination switch in direc-
tion of arrow1 past the resistance
point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system*”
(
page 316).iTo prevent smears on the windshield,
wipe with windshield washer fluid every
now and then even when it is raining.
!If anything blocks the windshield
wipers (leaves, snow, etc.), switch
them off immediately.
For safety reasons, stop the vehicle
in a safe location and,
remove SmartKey from starter
switch
or
turn off the engine by pressing
the KEYLESS-GO* start/stop
button and open the driver’s
door (with the driver’s door
open, starter switch is in posi-
tion 0, same as with SmartKey

before attempting to remove any
blockage.
Remove blockage.
Turn the windshield wipers on
again.
If windshield wipers fail to function at
all in combination switch positionI,
set the combination switch to the
next higher wiper speed
have the windshield wipers
checked at the nearest authorized
Mercedes-Benz Center.
